[GAVE (gastric antral vascular ectasia)]

Gastric antral vascular ectasia (GAVE) is an unusual but interesting cause of chronic gastrointestinal blood loss and anemia. GAVE was first described in 1953 by Ryder in the gastrectomy specimen of an elderly woman, as 'erosive atrophic gastritis with marked venocapillary ectasi'. In endoscopy, GAVE has unique appearance characterized by prominent erythematous stripes radiating in a spoke-like fashion from the pylorus to the antrum. Jabbari called it as 'watermelon stomach. GAVE is commonly misinterpreted as antral gastritis.

It is most common in the eldery women. It may be associated with cirrhosis in about 30% of cases. Common presentation is iron-deficiency anemia secondary to occult blood loss. Overt gastrointestinal bleeding in the form of intermittent melena and hematemesis is also possible. Histology (not necessary for a diagnosis) usually shows fibromuscular hyperplasia of the lamina propria, intravascular fibrin thrombi and an increase in the mean cross-sectional area of the lumen in mucosal vessels
